Precise seed taking device for precise seeding machine

Abstract

The invention relates to a precise seed taking device for a precise seeding machine, belonging to the technical field of agricultural machinery. The precise seed taking device comprises a seed box, a transmission shaft, a seed taking adjustment rod and a fan, wherein a seed outlet is formed in the bottom of the seed box; the transmission shaft is arranged at the top of the seed box through a mounting frame; a cam is arranged on the transmission shaft; the seed taking adjustment rod is movably mounted in the seed box below the cam through the mounting frame and a spring; the lower end of the seed taking adjustment rod extends into the seed outlet; the top end of the seed taking adjustment rod is connected with the cam in a contact manner. The precise seed taking device is simple in structure and novel in design; the problems that the existing precise seeding mainly depends on manual dibble seeding, and is low in efficiency, high in labor intensity, extremely high in consumption of crop seeds and low in working quality are solved; the precise seed taking device has active popularization significance on increasing of the crop yield, the use amount of seeds can be reduced and the planting cost can be lowered.

Description

technical field [0001] The invention relates to a precision seed picker for a precision seeder, which belongs to the technical field of agricultural machinery. Background technique [0002] With the continuous development of agricultural production technology, the requirements for agricultural machinery and tools are gradually increasing. Especially in sowing, agricultural machinery often needs to achieve precision sowing according to agronomic requirements, so as to improve labor efficiency and reduce the intensity of field management in the later stage. However, in actual production, due to the structural reasons of the existing seeder, it can only be used for sowing crop seeds with larger particle sizes, such as corn, beans, etc.; and for some crop seeds with smaller particle sizes, such as rapeseed and sesame , wheat, etc., due to the structure of the planter, it is difficult to control the seeding of the seeds, and the phenomenon of heavy plants after sowing is very se...
